I mean all three of those teams had major changes before and after their wins that can lead to their rise and fall. EG already got 2nd at Tokyo, had a rifler who a lot of people were calling the best fragger in the game as well as a map they were unbeatable on, EDG changed nobody to igl and picked up s1mon, and NRG picked up Skuba and brought back Bonkar. EG had their roster decimated, EDG were having internal issues with s1mon during champs even and still got third at Bangkok before benching him, and NRG have lost s0m who provided a lot of intangibles like vibes and mid rounding we have yet to see if they have a monumental falloff .
